The researchers at Massachusetts Institute of Technology (MIT) within the US found that if a stick is twisted previous a sure crucial diploma, then slowly bent in half, it can, towards all odds, break in two.
The discovering could have purposes past culinary curiosities, comparable to enhancing the understanding of the crack formation and easy methods to management fractures in different rod-like supplies comparable to multifiber buildings, they stated.
In 2005, physicists from France pieced collectively a idea to explain the forces at work when spaghetti – and any lengthy, skinny rod – is bent.
This preliminary break triggers a “snap-back” impact and a bending wave, or vibration, that additional fractures the stick.
Their idea appeared to solve the puzzle.
The reply, in response to the examine at MIT, is sure – with a twist.
They carried out experiments with lots of of spaghetti sticks, bending and twisting them with an equipment they constructed particularly for the duty.
“It will be interesting to see whether and how twist could similarly be used to control the fracture dynamics of two-dimensional and three-dimensional materials,” stated Jorn Dunkel, an affiliate professor at MIT.
